"Emily! What? You're just gonna walk away in the middle of an argument?" Derek called.
Emily stopped at the front door. She took a deep breath. She'd known this day would come. Ian Doyle was free and he was coming for her. She wanted to go out taking him down, not being slaughtered by his revenge. She couldn't let Derek or anyone get caught in the crossfire.
"Derek, you and me…" She took another deep breath, turning to face the man who showed her nothing but love and support, "We'll never work out."
"Why not? Give me one good reason why, Emily!" He said angrily. He was upset and he had every right to be, but she couldn't let his pain change her mind. She had to do this to save him, to save everyone.
"I'm no good. I have things in my past that no one can fix. No one but me, I have to fix things." She explained, hand still on the doorknob.
"PRENTISS!" He yelled, using her last name to get her attention, "I don't care what skeletons you have in your closet. Everybody's got em. Did you think I wanted the whole BAU finding out about my past? No! I didn't but they damn well helped me when I needed it, so let me help you! Explain what's so important, you're willing to throw out 2 years of our lives together!" He said approaching her, desperately trying to get her to stay.
"Derek… I— I cant." She said shaking her head. "I'm damaged goods." She said coldly, before opening the door and walking out on the only good thing she had left in her life.
